Product Overview
The Allegro A1318 and A1319 are linear Hall-effect sensor ICs designed for high-accuracy applications such as displacement and angular position sensing. These temperature-stable devices feature non-volatile memory for optimizing sensitivity and quiescent voltage output (QVO), ensuring sustained performance across a wide operating temperature range of 40C to 150C. They offer a voltage output proportional to the applied magnetic field, with a QVO adjusted around 50% of the supply voltage. Ideal for automotive and industrial applications, these ICs are available in miniature surface-mount (SOT23-W) and through-hole (SIP) packages and are immune to mechanical stress with enhanced EMC performance.
